FN Field Notes
Notes off the bench
Written up after the call, from what the unit was actually doing. If one of these gets your Sub-Zero running without us, that is a good outcome.
- 01 Six Grains on One Side of the Sammamish River, 1.2 on the Other: Reading a Redmond Ice-Maker Fault by Address Redmond runs two waters: roughly 90 mg/L, about 6 grains, on the city groundwater system, and roughly 20 mg/L, about 1.2 grains, on Tolt supply, divided by the Sammamish River. The same ice fault therefore starts with a different first check by address.
- 02 Sub-Zero Ice Maker Stopped Producing: A Redmond Diagnostic Order When a Sub-Zero ice maker quits, the module is rarely the fault. Work through supply, fill, freeze and harvest in that order and you will usually find the real cause before spending anything.
- 03 Sub-Zero Freezer Frosting Over Again: Reading the Defrost Circuit Frost sheeting the back panel of a Sub-Zero freezer within days of clearing it is a defrost fault, not a door problem. How to read the circuit, what usually fails, and when the part is worth ordering.
